The strapping machine provided by the present invention may, however, be embodied in many different forms and is not limited to the embodiments described herein. Rather, embodiments are provided so that this disclosure will be thorough and complete.
As shown in fig. 1, a strapping machine provided in an embodiment of the present invention has: the strapping assembly 1 and the rack assembly 2 are respectively provided with a main arm 11, the rack assembly 2 is provided with a workbench 21, the main arm 11 is positioned on the workbench 21, the rack assembly 2 is provided with a rocker arm 31 and a pedal 41, and the strapping machine is also provided with an auxiliary driving assembly which comprises the rocker arm 31 and the pedal 41.
In fig. 1 and 2, the main arm 11 is in the initial position, and in fig. 3, the main arm 11 is in the closed position.
Referring to fig. 1 and 4, the swing arm 31 is rotatably mounted in a plane parallel to the main arm 11, and the swing arm 31 has a grip 32 and a crosspiece 33, the grip 32 being located at the front end of the swing arm 31 and perpendicular to the plane of rotation of the swing arm 31, the crosspiece 33 being located at the rear of the main arm 11 and perpendicular to the plane of rotation of the main arm 11, and the crosspiece 33 being mounted to rotate with the swing arm 31. When the main arm 11 is located at the initial position shown in fig. 1, the user pulls the grip 32 to rotate the swing arm 31, the crosspiece 33 applies force to the main arm 11, the swing arm 31 rotates the main arm 11 from the initial position to the closed position, that is, the first action is performed, and when the force applied to the grip 32 by the user is removed, the main arm 11 is rotated from the closed position to the initial position by the return spring (not shown) to perform the second action.
One end of the pedal 41 is hinged on the frame assembly 2, the other end is connected and suspended on the frame assembly 2 through a spring 42, and a connecting piece 43 is arranged between the pedal 41 and the main arm 11. When the main arm 11 is at the initial position, the user can apply downward force to the pedal 41 in a stepping manner, and under the conduction action of the connecting piece 43, the main arm 11 starts to rotate from the initial position to the closed position, that is, the first action is executed, and after the force applied to the pedal 41 by the user is cancelled, the pedal returns to the original position under the action of the spring 42, and simultaneously, the main arm 11 rotates from the closed position to the initial position under the action of the return spring (omitted in the drawing), that is, the second action is executed.
Accordingly, the user can drive the main arm 11 to perform the first operation and the second operation by independently operating the swing arm 31 or the pedal 41, and after the second operation is completed, the swing arm 31 or the pedal 41 can be returned to the position before being operated, so that the next operation can be performed.
Because the crosspiece 33 is positioned at the rear part of the main arm 11, when the main arm 11 is driven to rotate from the initial position through the pedal 41, no interaction force exists between the main arm 11 and the crosspiece 33, and the pedal 41 and the rocker 31 are not linked with each other; similarly, when the main arm 11 is at the initial position and the user rotates the swing arm 31 via the grip 32 to make the main arm 11 perform the first motion, since the connecting member 43 is installed in such a way as to maintain the one-way transmission between the main arm 11 and the pedal 41, no interaction force exists between the main arm 11 and the pedal 41, that is, no interaction force exists between the swing arm 31 and the pedal 41 and no interaction force exists between the swing arm and the pedal 41 and no.
Preferably, the connecting member 43 is a connecting rod, the upper end of the connecting rod is provided with a vertical cross bar 44 (refer to fig. 1 and 5), the lower end of the main arm 11 is provided with an arc-shaped guide ring 12, the cross bar 44 is positioned in the guide ring 12, and the main arm 11 and the connecting member 43 are connected with the cross bar 44 through the guide ring 12 for transmission. As shown in fig. 1, when the main arm 11 is at the initial position, the cross bar 44 is located at the lower end of the inner wall of the guide ring 12, and when the main arm 11 is driven by the rocker 31 to perform the first action, the guide ring 12 moves downward relative to the cross bar 44, and there is no interaction force between the guide ring 12 and the cross bar 44; on the other hand, if the strapping machine is operated by stepping down the pedal 41 when the main arm 11 is at the initial position, the cross bar 44 applies a downward force to the lower inner wall of the guide ring 12, thereby driving the main arm 11 to rotate to perform the first motion.
Preferably, the connecting member 43 may be a length of the inelastic string connected between the pedal 41 and the main arm 11, the length of the inelastic string is such that when the main arm 11 is located at the initial position and the pedal 41 is in the natural state without external force, the string is in the straight state, so that when the operator steps down on the pedal 41, the main arm 11 rotates to perform the first action under the conduction of the inelastic string as the connecting member 43, and when the operator operates the binding machine through the swing arm 31, the main arm 11 performs the first action, the second generation of the inelastic string as the connecting member 43 changes from the straight state to the loose state, and no interaction force exists between the swing arm 31 and the pedal 41 and no linkage exists.
The above embodiments are provided for the purpose of allowing the operator to freely select a proper operation mode by simultaneously providing the swing arm 31 and the pedal 41 as the auxiliary driving means, and in the above embodiments, the two operation modes are independent, interlocked and non-interfering with each other. Obviously, it is also possible to choose only one of the rocker 31 and the pedal 41 to be provided on the strapping machine as an auxiliary drive assembly to achieve different embodiments.
The embodiments described above are described in more detail and specifically, but should not be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
